About Celestial AI

As the industry strives to meet the demands of the AI workloads, bottlenecks in data transfers between processors and memory have hindered progress. The Photonic Fabric based Memory Fabric provides an optically scalable solution to the ‘Memory Wall’ problem, enabling tens of Terabytes of memory capacity at full HBM bandwidths with low tens of nanoseconds of latency and extremely low power. The Photonic Fabric based Compute Fabric enables Terabyte class bandwidth between compute nodes at low latency and power. Photonic Fabric delivers a transformative leap in AI system performance, ten years more advanced than existing technologies.

Description

In this role you will assist in developing Celestial AI’s core photonic technology. You will contribute towards (i) generating invaluable experimental data for Celestial AI sub-systems and (ii) design new or optimize existing photonic components for Celestial AI’s photonic component library.
